"And how'd you raise the edge?" asked Hank, with interest. "Pile up snow? That takes time."

"I'd cut bricks of snow," was Joe's answer; "then, when they were built into position, I'd break the ice, if that's possible, and throw water on the outside face of the wall we've constructed. Talk about armour-plate on a ship! That'll convert our fort into a regular dreadnought."

Hank turned on an expansive grin for our hero's special edification, while even the austere Redskin smiled. "And these here snow bricks," said Hank, "you'd take 'em from where?"

"Just outside the island. That would leave a kind of trench all round, and so give the enemy a greater height to climb, supposing they got to close quarters."

"Which aer likely enough, seeing as they're so many, and kin scatter so as to make shooting extry difficult. Shucks, lad! Guess you've put the case nicely. To make good out here we've got to have protection more than rifles kin give us. We'll build that wall; seems to me it aer the first thing that's wanted."

Perhaps half an hour or more had passed since they reached the spot where they were now awaiting the enemy, and during that time the busy Indian had constructed a comfortable lean-to, while, as has been narrated, Joe had built a fire and boiled the kettle. There being no sign yet of the half-breeds, the whole party sat down about the fire to discuss Joe's suggestions, while that young fellow himself delved in one of the bags they always carried with them, brought to light a chunk of frozen meat which, in that condition, would have required a good-sized axe to cut, and placed it over the flames. Ten minutes later, when the frost was driven from it, he cut a number of slices, thrust his cleaning rod through them, and poised the rod upon a couple of forked sticks above the fire. As for the remainder of the piece of flesh, it was quickly frozen solid; for by this time the moon was up and the cold was intense.

"It aer nice to have a fire, and a hollow to sit in," admitted Hank, who, as a rule, seemed to be absolutely unaffected by extremes of temperature. Joe had, in fact, seen the little man cool and collected, and not inconvenienced in the slightest, even when working on the hottest day, with a swarm of mosquitoes about him; while the icy breath of this winter had passed unnoticed. "We aer in fer a cold time," said the little hunter, staring into the embers, "and seems to me that that 'ere wall aer wanted fer another reason besides fer keeping them skunks out. It'll make us as warm inside here as ef we was tucked in our blankets on the cosiest feather bed you ever thought of."

"While these men outside will freeze," added Joe.

"Not they!" came the instant answer. "Them critters is used to life up here. Wouldn't wonder ef they was 'way up by James Bay most winter times, and there the cold aer wuss perhaps. They've enlarged our shelter already, and likely as not they've built a fire right inside. As soon as they've had a meal they'll turn right in, and the dogs along with 'em. That'll send up the warmth and keep an Arctic cold out. But it's ten chances to one as they'll try to rush us before the morning. Now ef them steaks is done we'll tackle them, and then get to at building."

There was a delightful odour of cooking about the little island, the overhanging branches of the evergreen pines seeming to hem it in. Joe's mouth was watering before he declared that the meal was ready, and then, having handed a slice to each of his friends, together with a species of damper cake made from flour and water toasted on the embers, he fell upon the food himself with a gusto that told how fear had no place with him. A pipe completed Hank's contentment, then, the moon being now full up, and the enemy out of sight, the trio set to work to erect the walls of their fortification. With their long-bladed knives they cut oblong chunks of frozen snow with the same ease as one would cut butter, and then, leaving Joe alone to do the building, sent block after block of the material sliding to the position he had taken.
